2. Mo gels styling lauulu, fale talavai disinfectants, ma isi.

O le sauniuniga o le N-ethylene pheasone, e aofia ai laasaga nei: 1. O faʻamaʻi faʻafefeteina o le saunia o le faʻamaʻi faʻamaʻi e aofia ai le sulfate siliva, sodium alumini silicate, malala paʻepaʻe uliuli, amproof, ma le tele-oxide. Ole fua ole: 0.5 : 5: 3: 5: 10; Faatasi ai ma i latou, o le multi-oxides e lima faʻafefiloi o le lima faʻamaʻi lua -钒 ma le oxide, tin oxide, sex oxide, ma manganese dioxide; O se paluga o le lima oxidation dioxide ma oxide, lima oxidation lua -钒 ma tin oxide, lima oxidation lua -钒 ma manganese oxide ma manganese dioxide. O le faʻafefiloi o le dioxide oxidation lona fitu o le 0.2: 1: 2: 1. O laasaga o le gaosiga o faʻamaʻi faʻamaʻi o le: faʻafefiloi le sulfate siliva, amproof, ma le tele-oxides i le faʻatusatusaga, ona faʻaopoopoina lea o le 1 taimi le voluma o vai faʻafefe, fetuunai le tau o le pH o le sulfuric acid ma le ammonia vai i le 6.5 i le 7, ona faʻaopoopoina lea o le sodium silicon proportion. O malala paʻepaʻe e uliuli, faʻavevela ma faʻafefeteina e fai ai le fofo tutusa; faʻafefe i totonu o le vai taʻele ma faʻafefete le vaifofo e faʻagogo, faʻagogo i le 100-120 ° C mo le 6 i le 8h, ona tao lea mo le 3 i le 5h i le 400 ~ 450 ° C. 2. Sauniuniga o le N-hydroxyethylpylpyline (NHP) 1) Faʻafefiloi γ-butanol, tasi le ethanol, ma le ammonia2: tasi le ethanol: 0.2, ma tali i le 0.5MPa ma le 40 ° C., Faia se vaeluagalemu; 2) Faʻaopoopo le mole mole sieve o le 0.1WT% ma le 0.1WT% o le dilateyl dihal ether e faʻateleina ai le vevela i le 180 ° C e faʻagata ai le 12h i se tulaga taofia; mea ua faamatalaina e pei ona faamatalaina; o le a le mea ua taua? O le sieve mole o le 10xchemicalbook molecular sieve poʻo le 13X molecular sieve. O lenei metotia ua filifilia e pei o 10x molecular sieves; 3) decompression distillation, o le gaogao o le 0.095MPa, ma aoina le distillation o le vaipuna o le 210 i le 216 ° C. Pyrodorrone; 3. Le tali dehydration o le N-hydroxyetylpinol e faia le distillation sikoa maua i le sauniuniga o le N-hydroxyethylpinols i le ausa, fefiloi ma alkaline kasa, acetylene kasa, ma nitrogen e maua kasa paluga mea mata. Ole fua fa'afefiloi ole 1 : 0.5: 0.1: 0.1; Faʻafefiloi mea mata kasa i lalo o le tulaga o se reactor moega tumau o le faʻamaʻi faʻamaʻi i le vevela o le 350 ° C, o le mamafa o le 0.01MPa ma le saoasaoa o le kesi o le 50-300H-1, ma le faʻamalo o le faʻamalo i totonu o le faʻamaʻi moega tumau O le faʻamalosi e vevela i le 390 ° C. cephalopicone (NVP) oloa o lo'o fa'ate'a mai se masini fa'amoe. O kasa alkaline e le itiiti ifo ma le tasi o ammonia, methylemine, dihamine, trothalmine, ma ethimine. Fa'aaoga metotia su'esu'e chromatography kasa, e fa'avae i luga ole γ-butthite e pei o le tulaga i totonu, ethanol e pei o solvents, iloilo le N-ethylene cheedone oloa saunia e lenei metotia, fuafuaina le fua faatatau o le liua NHP, NVP selectivity, NVP tupe maua, lea kesi vaega vaega vaega vaega, lea kesi vaega vaega vaega vaega, o lea vaega kesi vaega o le tulaga o le chromatography, polyethylene tulaga tulaga: faʻalauteleina fofo faʻapipiʻi, faʻapipiʻiina le nitrogen, silicanerization 102 paʻepaʻe eseesega, gasification potu vevela 280 ° C, TCD detector vevela 165 ° C, koluma, koluma, koluma O le vevela o le 190 ° C; fuafuaina e ala i le au'ili'iliga o le kesi chromatography: NHP fua faatatau liua o le 92.8%, NVP filifilia 91.5%, ma le NVP tupe maua o le 85.6%.
